Myers,'Roanoke, Va., assignerv to The Standard Stoker Company, Incorporated,v a Vcorporation of Delaware Application February 5, 11932,' Serial No. 591,124 Renewed August 18, 1934 s claims.l (cries-15)V This invention relates to conveying mechanism and more particularly to fuel conveying mechanism for a locomotive stoker whereby fuel isconducted from a source of supply, as from a tender,

motive.

It is the general purpose of the invention to provide a novel stoker `conveying systemV that is simple, compact and light in construction, eiiicient in operation, easily assembled andY installed on existing types of locomotives and composed of a minimum number of moving parts.

More specifically it is the purpose of the invention to provide a' stoker conveying system comprising a transfer conduit pivotally mounted intermediate its ends on the tender and a riser conduit including telescopically connected sections, one section thereof being rigidly fixed on the locomotive, andthe adjacent ends of the transfer and riser conduits being iiexibly con-A nected. Y v

Further objects andadvantages'offthe invention willy vappear from the ollowing'description taken' in connection Awith the accompanying drawing, in which I Fig. 1 is a longitudinal, central, vertical section through the rearward portion of a locomotive and the forward portionof a tender, with a Stoker in similar sectionapplied thereto; and

Fig. 2 is Va longitudinal, central vertical sectional view showing a modied form of the yin vention illustrated in Fig. 1.

In the drawing, the locomotive is represented generally by the letter A, its `tender by the letter B, the coupling member joining the locomotive and tender by C andthe stokerby D.' The locomotive is provided with theiirebox 10, the boiler backhead 11 having a ring opening 12 therethrough `and the boiler mud ring 13. The tender is provided with the fuel bin 14 having a licor or deck 15 with a longitudinally centrally located aperture 16, and a plurality of slidably mounted plates 1'7 normally closing the aperture 16 andwhieh may be moved from coveringposition to regulate the delivery of fuel from the bin. i

Movably mounted on thetender is a rigidconduit section designated as a wholeby the numeral 18 and Ywhich includes the open mouth trough 19, located below the fuel bin 14, the forwardly and slightly upwardly inclined conduit 2l) and the interposed enlarged spherical member 2l rigidly secured to each other at their respective adjacent ends Vin any suitablemanner, 'as for example, by means 'of vbolts passing through tially horizontal transversely extending axis.

the flanges at their adjacent end. AThe front Wall 22 of the 4trough 19 is provided with a discharge'opening 23. `Mounted in the vtrough 19 and extendingzforwardly through -the opening 23 into the spherical memberl2l isa c onveyor screwY 24 for advancingifuel therethrough. The screw 24 is driven from itsv rearward end infamanner well known in the art and is therefore not particularly illustrated. A` conveyor screw 25 .is mounted in theoonduit 2() and extendsfrinto the'spherical member 21 whereitis connected with' the forward end of the conveyor screw by a universal joint 26. Y

VvThe portion of thestoker mounted onthe locomotive includeslfa .riser conduit 27 extending upwardly and forwardly through the locomotive cab deck 28 from va'point therebelow tothe lower :portion ofthe ring openingflZ.V The riser conduit `27 comprises aan' upperr sectionV 29 and.. a lower section telescopically'connected.I The upper section 2,9 ofthelriser conduit 27 is rigidly" mounted on the locomotive by suitable means, as by the bracket 3l supporting it from the mud ring 13. .The lower Vend ofthe lower section 30 `curves,'the conduit 18 is mounted intermediate its ends to rotate or pivot. about a substantially vertical axis as well as to rock about a substan- For this purpose a bracket 34 is rigidly secured to the trough 19 about midway between its forward and rearward ends. The lower portion of the bracket 34 comprises a horizontally and transversely'extending member 35 received in the angle members 36. Theranglel members `36 Vwhich extend forwardly and downwardly for at-V tachment to an adjacent portion of the tender Vare supported adjacent` the bracket 34 by substantially channel shaped membersSL Y The unders'idesV of the rend portions of the member` `35 are preferably curved so that the bracketv and conduit may rock about a transverselylextending horizontal axis.

Interposed between the angle membersfand 1 the channel'members 37 is a transverselyextending bar V38 which underlies and isadjacent to the member 35 of the bracket. Il'he -bar 38 .and member 35 are provided with registering apertures for receiving a vertical pin 39 which, although it enables rotation or pivoting of the conduit 18 about a vertical axis, prevents longitudinal movement thereof. The outer ends of the member 35 are also curved so that when the bracket 34 and conduit 18 rotate about the pivot pin 39 suiiicient clearance will be provided between them and the angle members 36.

Located at the upper end of the conduit 27 and disposed in the firing opening 12 is the distributor head 40 and extending forwardly therefrom is the distributor plate 41. The forward wall of the distributor head 40 is provided with` a series of jet openings 42 through which pressure fluid, as steam is ejected for impelling fuel over the distributor plate 41. Pressure fluid is admitted to the distributor head 40 throughy any suitable number of supply Vpipes 43.

Above the upper end of the conduit 2' 7v is a door frame or casing 44 having top and side portions surrounding corresponding portions ofthe firing opening, rthe casing being preferably' formed as a separate unit instead of as an integral part of the conduit. Pivoted doors, 45 are provided for closingv the rear of the casing 44 Vand constitute, in effect, a continuation of the rear wallof the conduit 27. Y

- `In figure 2 is shown Aa slightly modified-form of the invention differing from the preferred form inlthat a. screw conveyor 46 is mounted in the 4riser conduit and is universally connected at its lower end to the forward end of the screw 25.
